On the 11th of May I set up a
sole proprietorship with the name AhlCode.
It is meant to legitimise and properly handle any income coming from my side businesses. The main
aim at this point is to get some money back to compensate the server costs of things I host. But I
wouldn’t complain if it resulted in some little profit also.
Configuring Elixir applications is a common problem point for new developers and I’ve seen many
questions about it in the community chats. So I thought to write down my knowledge in case it helps
I’ve long had certain issues with modern
web development, and I even wrote a
little tool of my own to help
me manage such an environment. So I look for ways to minimise the complexity of my setups while still
maintaining some modern conveniences. Now I’ve started to use a setup that relies on TypeScript and
modern browsers’ builtin features. This is a very minimal setup consisting just of TypeScript, plain
CSS, and maybe a tiny build script.
After moving Code::Stats to its own server, the old Online.net box this
blog was running on was going to waste, and more importantly, wasting my money. So I got a new
tiny box from Hetzner and finally got over to dumping the blog on it. But of course I had to use
the opportunity to also refactor it a bit…
Unicode contains a lot of great and useful things. And as things tend to go, people find creative uses for
them. It’s currently trendy to use some of Unicode’s special characters for “font effects”,
𝕝𝕚𝕜𝕖 𝕥𝕙𝕚𝕤 𝕖𝕩𝕒𝕞𝕡𝕝𝕖
(assuming you have good font support, you should see cool double struck letters reading “like this
example”). There are easy converters available for finding out the best
I was doing some Node.js V8 profiling work at the office near the end of the day and noticed my profile processing was taking a long time.
I figured it is just processor intensive and left it running for the day while I went home. To my surprise, the next day it was
still running! htop showed me it had accumulated 12 hours of CPU time and was still not finished. This led me to track down
a related issue and how to fix it.
I was wondering today how to filter uWSGI logs based on the request path because we had an endpoint that was filling our
logs with meaningless information. At least for me this was surprisingly difficult to find. So
here is an example command line option:
The log-filter flag takes in a regular expression that is used to include lines that match the
filter (so it works as a whitelist). To filter lines that don’t contain something, you can use
a negative lookahead.
So it turns out mechanical keyboards are like a drug to me. After I tried my first one at work, I
had toget more.
At the same time I started to pay attention to the ergonomics of my typing. I noticed that when I
typed a lot, my fingers and wrists would start getting fatigued quickly. My typing style also had
space for improvement, with my left hand stealing a lot of work from the right hand and my fingers
hitting the wrong keys. I was a touch typist, but following my own style that was hardly optimal.
All this got me looking for something different, an ergonomic keyboard.
